For example, one episode has the main characters eating cereal, playing Rock-Paper-Scissors over a chair, summoning an inter-dimensional monster after getting one hundred ties in a row, and then having everything turn back to normal. And this was on Mordecai and Rigby's first day at work, no less.

Just a note, most of the main characters' designs come from J.G. Quintel's previous animated student films. Mordecai and Benson were featured in a Mushroom Samba in 2 in the AM PM and Pops as a lollipop ambassador in The Naive Man From Lolliland. They're both well worth checking out, but definitely not for kids.

In an attempt to "age up" Cartoon Network, this show aired in September of 2010 and is currently being renewed for a fourth season, which should continue through 2013. New episodes used to air on Monday nights at 8:15 (7:15 central), but as of 2012 they air at 8:00 (7:00 central) on Cartoon Network. Getting Crap Past The Radar page here. Also check out the Character Sheet here.

Absurdly High Stakes Game: "Skips Strikes" has Rigby making a bet with Death: If Death's Team wins he'll get the team's (which is everyone working at the park except Muscle Man and Hi Five Ghost) souls and if Rigby's Team wins he gets... a bowling ball filled with souls. Mordecai and Benson aren't happy about this in the slightest.

"Over the Top" has Skips arm wrestling Death for Rigby's soul.

In "Slam Dunk", Mordecai eventually bets his computer privileges for life on a basketball game just so he can help Margaret make a website in hopes of impressing her.

An Aesop: From the episode "Mordecai and the Rigbys", Mordecai and Rigby noticed at the end of the show that their future selves stayed famous through lip-syncing. Mordecai makes a speech about the issue.

"Video Game Wizard" where Rigby gets jealous that Mordecai chose Skips as his partner for the video game tournament is an affectionate parody of The Wizard (film). It even has a crappy power glove knockoff as the grand prize.

Alien Geometries: In "Brain Eraser", the world of Mordecai's memories is a strange place.

Also their combined efforts in defeating the physical manifestation of "Summertime Lovin'".

In "A Bunch of Baby Ducks", the baby ducks fuse into a giant duck person to defeat the creepy guy with the van.

Aloof Big Brother: Don, who is taller and more mature than Rigby, actually subverts this, since he is actually younger than Rigby, as well as extremely affectionate towards his sibling. Rigby was jealous and angry that his friends liked Don more and that they think he is the older brother, so he rejected Don's affection and hated having to see him. Which makes Rigby the Aloof Big Brother!

And I Must Scream: Apparently, viral videos have their stars trapped inside of them. They're forced to repeat their injuries and mistakes over and over again. Until our heroes come to their rescue, of course.

Angst Nuke: When Benson finally releases all his pent up anger in "Think Positive", the results are explosive.

Balloon Belly: Party Pete after drinking several Radicolas which gave him strange powers. After finding out Benson was going to return to the park to see what all the commotion was about (they were having a party without Benson's say so), The gang had to keep giving Party Pete Radicolas so he'll burn out in order to get rid of him before Benson showed up, thus ending Mordecai and Rigby's party with a bang.

The Night Owl gets one after the guys make it back to the time machine and escape him. The present Night Owl gets one when they come out of the portal crashing down on his billboard and car, ruining his plan.

Big "Shut Up!": Rigby, very often. A variation of this that he also uses very often is, "STOP TALKING!!!"

Bilingual Bonus: In the opening of "Fortune Cookie", when everyone is at the Chinese restaurant, we get a couple of shots of the Dim Sum receipt. It has four rows, labeled with the Pinyin characters for "small", "medium", "large" and "king".

Bishie Sparkle: Starla sees Mordecai with these when she falls for him.

Compared to the rest of the series, "My Mom" seems to be the most Regular Show of the bunch. Short of Muscleman's brother riding his truck out of hell, it's a pretty quiet day all things taken equally.

"Ello Gov'nor" also is pretty normal, short of a video rental store employee dressing up as a haunted taxi.

"Muscle Woman"'s only seriously weird aspect is how much of a bitch Starla is.

"Temp Check" doesn't have much weirdness, except for the temp worker being a shapeshifting doppelgänger.

Aside from Mordecai and Rigby being turned into ghosts by Hi Five Ghost's brother, "See You There" is a relatively straightforward episode.

Another comes from "A Bunch of Baby Ducks". Aside from the baby ducks transforming to a giant duck and destroying the duck collector after he hurt their mom, it seems like a normal day.

"More Smarter" is pretty normal too. There's no monsters or vortices, they solve their problem on their own, and no one was in any real danger.

"Karaoke Video" is probably the most normal episode of Regular Show as of Season 2. Nothing strange at all happens, unless you count the short scene where everyone appears to be fighting in some abstract void thing.

It's safe to say that the second season cut back a fair bit on the weirdness... or at least made it more of an everyday occurance that doesn't expect as much fanfare.

Breath Weapon: Benson unleashes a torrent of pure, pent up rage at Mordecai and Rigby during "Think Positive" in the form of a mouth laser.

To a lesser extent "The Power", which involves asking for raises to... hire someone else to fix a hole in a wall.

Butt Monkey: Rigby. Considering he's been killed three times in the series, he fits this trope perfectly.

Call Back: In "Grave Sights", Benson asks Skips to set up the chairs, making an obvious callback to "Just Set Up the Chairs".

In "Benson Be Gone", Maellard complains to Benson about snacks disappearing from the snack bar, holes in the walls, and five hundred dollars worth of prank phone calls, which are all references to the episodes "Rigby's Body", "The Power" and "Prank Callers" respectively.

In "Camping Can Be Cool", Mordecai and Rigby bring the Super Extra Premium Hot Dogs from "Meat Your Maker" to eat on the camping trip.

"Stick Hockey" seems to be a whole episode callback to a scene in "Benson Be Gone", in which Benson starts warming up to the Mordecai and Rigby over the Stick Hockey game.

The Unicorns are back in "House Rules", prank calls are also referenced.

Mordecai also threatens to ruin No Rules Man's only good eye with a laser pointer. Everybody knows they aren't regulation.

Subtly, when payday is first shown in "High Score", Mordecai complains about how they're essentially receiving doggy bags full of change, and ask to at least get an envelope. Later, in "Temp Check", they receive their pay in an envelope.

In "The Power", one of the things Rigby sends to the moon during the Cutaway Gag is "a bunch of baby ducks." There's a later episode with that exact name.

The Ferguson Convention Center from "Video Game Wizard" is named after Garret Bobby Ferguson, from the episode "High Score". A bust of him is even seen outside the building.

In "The Best Burger in the World", the burger truck crashes into the Crash Pit from "Terror Tales of the Park".

They do a much better job with a tape of the 1982 World Dishwashing Championship

Can't Get Away with Nuthin': The entire plot of Regular Show is made up of this. The show starts out with something normal. Set up these chairs, go buy me a grilled cheese sandwich, learn to play guitar by the end of the episode, etc. However, just due to the world they live in, this somehow turns into a video game almost destroying the world, having to stop a black hole, and your future selves destroying your concert, just to name the outcomes of these examples. And of course, by the end of the episode (excluding "Prank Callers") everything is back to normal.

Character Development: "Benson Be Gone" has Benson come to understand Mordecai and Rigby more. And it sticks, afterwards, he's shown to be noticeably more tolerant of them and doesn't fly into a rage over them as often. In "Jinx", he actually accepts an apology from them, where before he'd not have given them the time of day. Especially since earlier, Rigby sent him in a moment of Unstoppable Rage, which Benson didn't take out on Rigby himself. Newer episodes also have him leading the group in "down time" activities such as game night or paying for drinks for everyone at a bar, showing he's lightened up more.

Rigby has grown much closer to Eileen; in "Yes Dude Yes", he eagerly suggests going to the movies with her, while in "Do Me a Solid", he only accepted a date as a solid, and did everything possible to sabotage it.

Margaret was a Flat Character compared to the other recurring cast, that is until "Do Me a Solid" where she's revealed to be a down-to-earth character (the unusual circumstances don't faze her nearly as much as one would expect).

Benson, Skips, and even Muscle Man and Hi Five Ghost have had a good bit of character growth over the series as well, the group becoming kinder and more friendly with Rigby and Mordecai, making some of their early scenes a bit strange to how they are now. This is especially clear with Benson, who doesn't go into a rage as often. Recent episodes even have him doing things like organizing game nights for everyone and taking everyone out to a bar with the drinks on him, showing he's lightened up considerably.

Button Mashing really works in video games, but only for shooting, not for leg control... normally.

The grilled cheese.

"Laser pointers?! That's not regulation!"

The celebratory hug, or lack thereof.

Two Words: "PLAYCO ARMBOY".

Muscle Man's sporting equipment in "Grave Sights".

Chess with Death: Arm Wrestling with Death, in Skips' case. He challenged Death to restore Rigby back to life, whom Skips had killed in the first place. If he lost, Death would've claimed his immortal soul.

A blinking contest with Peeps, a floating eyeball monster to get him to leave in "Peeps". If they'd lost, he'd have taken all their eyes.

Moredecai and Rigby had to babysit Death's son in order to save Muscle Man from having his soul reaped. The specific condition was to have him sleeping by 8 PM when Death and his wife got home from their anniversary date.

Continuity Nod: A very small one. In "Just Set Up the Chairs", Benson screams that he will never trust Mordecai and Rigby to do something as simple as setting up the chairs ever again. In "Grave Sights", he has Skips set up the chairs instead.

In "Bet to Be Blonde", a pair of "Mordecai and the Rigbys" t-shirts can be seen in Mordecai and Rigby's closet, calling back to their fake band in the episode of that name.

In "Yes Dude Yes", we see Mordecai finish telling CJ about the events of "High Score".

Muscle Man hosts a fake party, gets Mordecai and Rigby turned into ghosts, and fakes a heart attack after Rigby accidentally spilled soda on him. After almost choking to death.

"Over the Top". Skips isn't too pleased about Rigby beating him in arm wrestling, especially after finding out he used an arm brace. So he forces him into a rematch, yanks out the brace, then instead of leaving it there, smashes him through the table, killing him. Skips realizes this though, and puts his own soul on the line to bring him back to life.

The Wizard from the Halloween Special turns Rigby into a house and brutally murders the entire cast just because Rigby egged his house.

Not to mention egging the house Rigby rather harmlessly, giving Rigby enough time to lampshade the topic... JUST before the wizard drops a house-sized EGG and drenching him in egg yolk as he screams in horror. "The End".

Doppelganger Spin: Used by Chong in "Stick Hockey" as one of several methods to gain the upper hand in the final round of stick hockey.

Dramatic Irony: In "Cool Bikes", Benson admits that Mordecai and Rigby are the coolest guys he knows. In any other context this would be sweet, but the viewer knows that Benson just unknowingly secured them a guilty verdict.

Drunk on Milk: Every time there's a bunch of soda cans around, they mean beer.

Dying Moment of Awesome: Utopia performing a Heroic Sacrifice in "Benson Be Gone" to take out Susan and Wedgie Ninja's sacrifice in "Go Viral" to save Mordecai, Rigby, and Pops from the Warden of the Internet, destroying her in the process.

Ear Worm: In-Universe example: in "This Is My Jam", Rigby gets "Summertime Loving, Loving in the Summer (Time)" stuck in his head, to the point that the song sings itself whenever he opens his mouth. Not singing it, but playing on its own. Eventually the song manifests itself into a physical form and starts driving everyone nuts. And then the gang decides to come up with an even catchier song to rid of it... "Aw snap! Aw snap! Come to our macaroni party then we'll take a nap!"

Which then gets stuck in Rigby's head just like the last song, causing everyone to groan.

When you tie in rock paper scissors 100 times, it summons a black hole that apparently leads to a monster's dimension. The glimpse of the monster is… disconcerting.

In the name of all that is holy, do not play with the wires of the Destroyer of Worlds arcade game.

Father Time from "It's Time" is one. He is a being made entirely of clocks who lives at the end of time, and was actually a rather nice guy and was willing to let Mordecai off with a warning and press the Reset Button for him.

The Snow Monster. He's made of snow, breathes fire from a jawless mouth, and creates one of the scariest moments of the show.

Actually, the Book of Park Records could qualify too, as it gave a Necronomicon vibe when they touched it, and can alter reality (at least within the park).

Peeps from the self-titled episode. He's a giant floating eyeball that can summon a huge number of smaller eyeballs from his body and threatened to watch everyone till they died. When they made a deal to get rid of him, he wanted all their eyes if he won.

SUSAN. The worst part is how normal she seems before turning her head 180 degrees and going One-Winged Angel.

It's also the main thing the Creepy Doll in the Halloween special does.

Faceless Masses: Averted, in almost every crowd shot the background characters are drawn about as detailed as full on screen ones, although they are often duplicated, mirrored and huge crowds are usually not animated.

Fail O'Suckyname: In "Trash Boat", Rigby decides to change his name to two random words after seeing a news report on a rock star who did the same thing. The name he comes up with, Trash Boat, is... less than inspiring, and he spends the rest of the episode trying to get it changed back.

Fake Brit: Future Mordecai and Future Rigby in "Mordecai and the Rigbys". They lose the accents right before the two of them are destroyed by Present Mordecai.

Furry Confusion: Subverted in "A Bunch of Baby Ducks". The titular ducks seem to be non-anthropomorphic at first, but quickly pick up humanlike behaviors (like karate chopping) from Rigby, and their mother speaks English.

Played straight in "Skunked", with Mordecai and Rigby picking up roadkill in the park and even PLAYING A BINGO GAME USING THE DEAD ANIMALS, though technically it was created by Benson to motivate them to work; they can't stop working until they get Bingo.

"The Mississippi Queen". A concoction so absurdly spicy that Mordecai, Rigby, and Benson spent the rest of the party they were attending experiencing a Disney Acid Sequence played to the tune of "Mississippi Queen" by 70's rockband Mountain. It even came with a little umbrella.

Rigby's favorite internet video is of an ostrich kicking an old man in the balls.

Mordecai does this to GBF. But since said champ is basically a head with arms and legs, the champ reacts with "my chin!" (though "chin" is "penis" in Japanese)...

Subverted and played straight in "Rage Against the TV". In Mordecai and Rigby's video game, the duo are punching one of the games' bosses in the junk. As in the miscellaneous things he is carrying. Later, Skips gives one to The Hammer with a chair.

Skips perform one on a zombie. It doesn't work.

Half-Dressed Cartoon Animal: Rigby started walking around naked one day. His brother thought that was so cool, he hasn't worn clothes since.

Hipster: In "Cool Bikes", Mordecai and Rigby dress in this style to be cool. The stack of Brain Explosion records they swear upon in court is even a Call Back to Mordecai's own infamous hipster moment in "This Is My Jam".

"I can fix this" from the hot dogs episode. First, it's Rigby trying to fix everything that he's messed up but only messing it up worse. Then it's Rigby trying to keep Mordecai from dying. Then when Rigby brings up who bought the premium hot dogs...

There's also "I wouldn't want to ruin the surprise" from Future Mordecai in the episode "Mordecai and the Rigbys" when the regular Mordecai asks if he ends up with Margaret in the future. Mordecai throws it back at him in his Shut UP, Hannibal speech when he breaks up the band.

"Don't blink!" in "Peeps". First said by Peeps to Mordecai when Peeps starts growing extra eyes to tease Mordecai into blinking, and then by Mordecai to Peeps when it finally looks like Peeps is going to give in and blink.

Jerkass: Benson, by far and Muscle Man. Rigby and Mordecai can act like this a lot to each other, if they get on each other's nerves too much.

The Unicorns.

In "The Best Burger in the World", Benson makes Mordecai and Rigby work on all their extra jobs that they slacked off on. Despite there being a time limit to get said burgers. So he gives them the most work, and honestly expects them to not try to get burgers. Finally at the end of the episode, he eats both which they bought as punishment. Uh Benson... you could have had them gotten the burgers before and then have them do the work. Instead of being a jerkass...

Mordecai and Rigby in "Caffeinated Concert Tickets". They not only broke a contract with the Coffee Bean man, but they also added insult to injury with a "The Reason You Suck" Speech!

In their defense, the contract consisted solely of the word "Coffee" written over and over, and the interpreter refused to translate it until it was too late. Not to mention they came at Mordecai and Rigby with a chainsaw.

Also, near the end of the episode, Mordecai and Rigby fell asleep anyway. Though they actually got into the concert, they fell asleep through the whole performance.

Karmic Transformation: Egg a wizard's house, be cursed to turn INTO a house. Poor Rigby learned this the hard way in the Halloween special.

Kill'Em All: According to Benson, the only way to get rid of unicorns.

The Destroyer of Worlds too.

Skips: You fools! Destroyer of Worlds will kill us all!

The final story in the Halloween Special has this happen with the entire cast.

Knight Templar: The Warden of the Internet. Ok, wanting the internet to be used responsibly, that's an alright motive. Confining anyone who makes a viral video to a Fate Worse Than Death? Yeah, that's insane...

Konami Code: Used to dodge bottles being thrown at Rigby's character in a Rock Band style video game.

Line-of-Sight Name: In "Trash Boat", Rigby decides to change his name to two completely random words. He looks over at the overflowing trash can, then at the painting of a sailboat on the wall, and hence the title of the episode.

There's a Hard Work Montage to the tune of Loverboy's "Working for the Weekend" while trying to save up enough money to go to a concert.

In "Death Punchies", Rigby learns to Death Punch to "You're the Best" by Joe Esposito.

There's also Mordecai's, Rigby's and Benson's slack off sequence, all done to the tune of an instrumental song based off of Boston's "More than a Feeling".

Mordecai and Rigby end up starting a bar fight over possession of a karaoke tape with the owners of the bar while Pops sings "Footloose" by Kenny Loggins.

When Mordecai, Rigby, and Benson attend a party, they drink a spicy concoction called the "Mississippi Queen", named after the song by the rockband "Mountain". They spend the rest of the party in a Mushroom Samba while the song plays.

Mr. Exposition: Skips, when he gets involved in the current trouble of the episode, usually knows exactly what's going on and explains it further and how to solve it. Being a few thousand years old may have something to do with this.

Nice Job Breaking It, Hero: Rigby is usually the one who causes the crazy bleedly-blah to happen in the show. By this point, it should be obvious that Rigby ruins everything he touches, though he does make up for it by fixing most of the mistakes and problems he creates such as giving up the chocolate cake to save Skips' life and using mustard to defeat cannibal hotdogs. Examples include...

sending Skips to the moon, which almost got him and the rest of the cast killed by a giant monster in "The Power".

letting the Destroyer of Worlds loose (despite Skips and Mordecai's warnings) in "Just Set Up the Chairs".

signing the contract that almost made them lose their concert tickets, though it technically wasn't his fault since he couldn't even read it, in "Caffeinated Concert Tickets".

interrupting Skips' spirit dance in "Free Cake".

nearly making Mordecai freeze to death in "Meat your Maker".

breaking the audit machine nearly getting the park deleted in "Don".

alluding a bodybuilder without his body that his own body was still available in "Rigby's Body".

Mordecai kicks off his share of weird events as well, though it's usually due to pettiness instead of outright idiocy. In both "Death Punchies" and "It's Time", it's his pride that goes before the fall. Rigby's, that is.

Benson gets one in "Peeps", when he keeps improving his security system to stop Mordecai and Rigby from slacking off (justified though) and ultimately doesn't read the fine print and invites an Eldritch Abomination to spy on the park's workers for the rest of their natural lives. Ironically, the very thing he tried to stop them from doing is what got rid of it.

Skips in "Over the Top", when he literally kills Rigby, thus forcing him into an arm wrestling match with Death himself to bring Rigby back from the beyond.

Mordecai: Destruction of park property?!Rigby: Oh, yeah, that one time!

The solid worth ten solids that Rigby made Mordecai do. All we know is that all who witnessed it were shocked and repulsed, and it involved Mordecai squatting down and making car sounds. Fan speculation says that it was either him laying an egg or LITERALLY "doing a solid" (taking a dump).

Of Corpse He's Alive: The episode "Weekend at Benson's" has Mordecai and Rigby having to "escort" an unconcious Benson to a party after accidentally knocking him out cold at work.

Off-Model: The pilot episode showed up again later with some added parts to lengthen it to fit with a standard episode. Between the new scenes and the old scenes, characters change appearances pretty noticeably, due to the pilot having a looser animation style.

Older Than They Look: As of "The Night Owl", Mordecai, Rigby, Muscle Man, and Hi Five Ghost have aged another 2200 years, having been frozen with liquid nitrogen, unfrozen in the year 4224, and then time-traveled back into the past. Potentially subverted if the show followed the other group from the end on.

Skips.

Techmo. Considering that Skips fixed his arm back in 1783, that would make him well over 200 years old.

Subverted; although every video game shown so far has had retro graphics, this seems to be a stylistic choice, befitting the show's Retraux style and suggesting that maybe everyone in this world is just a retro gamer.

Lampshaded in Sarcasm Mode, when Mordecai and Rigby comment on the graphics and how the title screen looks just like the box.

In "Over the Top", they're even seen playing what appears to be an 8-bit version of Guitar Hero.

This is all especially subverted by the fact that Mordecai and Rigby very clearly have a Sega Master System Mark 1, which is most certainly an obscure version of a games console to have.

Benson: It's almost 8 o'clock. Kill the lights!Muscle Man: Woohoo! Skips is going to be totally surprised when he walks in and sees us totally naked!Benson: ...it's not that kind of party, Muscle Man.Muscle Man: Oh. (beat) Don't turn on the lights.

It's the semi-disturbing zipper sounds right before Muscle Man's quip that really drive the joke home.

The way Benson says his second line in that scene, like this is a regular occurrence and he's really just getting sick of dealing with it, is fairly priceless as well.

Twice in "Rigby's Body", once by the bodybuilder and again by Skips. His nipples light up.

Mordecai gets one too when he daydreams in "Meat Your Maker".

Percussive Maintenance: Skips' main method of fixing things is to hit it with a hammer. To be more specific, he carries a hammer that he's able to use as a universal tool to fix almost anything, regardless of how big or small it is, including computers.

Petting Zoo People: Mordecai is the most obvious example, but Margaret and several background characters also qualify.

The Power of Friendship: That seems to be the theme in "Eggcellent". Even when Rigby was in a coma, possibly never to wake up and even may die, Mordecai still keep his promise to get that hat for him. Then the other Groundkeepers came around for Mordecai when he couldn't do it alone and helped him practiced to win the hat. When Mordecai won the hat, he put it on his friend's head, which woke him up! It wasn't just because of the hat, it was also because of Mordecai's loyal Friendship for Rigby!

The Power of Rock: The battle between Mordecai's band and the Summertime Song is manifested as two ethereal rockers using their guitars as swords.

Pops' Realms of Darthon character, a cybernetic cowboy, utilizes a keytar as a weapon which shoots Frickin' Laser Beams when played.

In "Peeps", Benson asks for the most powerful security system Peeps will offer and is told to sign a binding contract. He's so angry he doesn't read it first and ends up summoning Peeps himself (a flying eye monster). Peeps later reveals the contract states he can watch them till the day they die.

In "But I Have a Receipt", Mordecai and Rigby try to return The Realm of Darthon but they didn't read the fine print. They already opened the game.

Reality Warper: The Power grants people... the power to do anything they want. Also, the Master Prank Caller, who should not be riled.

Reality Writing Book: Forging the park records has this effect. Mordecai and Rigby do it to trick Benson into giving them a raise, but Rigby overdoes it, resulting in the park being attacked by a snow monster.

Recurring Character: Other than Margaret, Elieen and Mr. Mallard, there's also Pa (the man who was kicked by the ostrich in "Grilled Cheese Deluxe") and one of TV Store Warehouse spokesman (the bald one)

Retraux: Everything has a very '80s feel--any video games that show up are extremely retro and/or arcade-based, and if a licensed song shows up it's guaranteed to be an '80s hit--but it's set in the present. "Prank Callers" places it after 2004 somewhere.

In "Cool Bikes", Mordecai and Rigby become so cool that it threatens to create a coolness singularity which will collapse Earth into a coolness black hole and destroy the universe.

In "Fortune Cookie", Benson has such bad luck that he loses the park to a sorcerer who then immediately grows over fifty feet tall and begins to literally suck up the entire park into his fanny pack. Yeah...

Crossing a red wire with a blue wire on a secret arcade machine unleashes a pixelated demon to the world.

Wearing a mullet and cutoff jeans gives you fists of ultimate destruction.

Underground stick hockey tournaments to the death, complete with fire shooting out of the ground and decapitations, have been going on for at least a decade.

Shallow Love Interest: In the entire first season, not much is known about Margaret, except she's nice and has a good set of lady pecs. Justified in that Mordecai himself can't seem to get past his shyness and learn more about her besides how attracted he is to her (note that he's always completely surprised about her boyfriends and entertainment preferences).

Margaret has been shown to be pretty shallow too. In "Brain Eraser", she becomes more attracted to him, believing he's been "working out" after he ignores her in a brainless stupor.

In "Yes Dude Yes", she only shows interest in Mordecai when she thought he was seeing CJ... how much more Shallow can you get?

Skewed Priorities: Dude, you kill the Destroyer of Worlds! I'm gonna go get the chairs!

Slice of Life: The show is basically about the lives of two best friends who are groundskeepers. Simultaneously a Work Com, as they live where they work. Every episode so far has had something to do with their job, although it's usually not what Mordecai and Rigby are interested in.

Smelly Skunk: A Jerkass one tries to turn Rigby into a skunk. Well... sort of, he's a Wereskunk whose spray transfers his curse in addition to smelling terrible. He's cured along with Rigby in the end, but it's implied he died in the process.

Soundtrack Dissonance: A bar brawl back by an excitable old man singing a karaoke version of "Footloose".

Space Whale Aesop: Eat healthy or your body will quit on you as in your body will rip your soul out and run away. Also happens if you exercise too much.

Spinning Out of Here: In the episode "Dizzy", when the characters spin around until they fall over, they are sent to a bizarre otherworld.

Suspiciously Specific Denial: In "Peeps", when Mordecai list responsible things Benson can't trust them to do, Rigby "helps" by mentioning that they also can't be trusted to not fart in Benson's coffee when he's not looking.

Sword Cane: The poacher in "A Bunch of Baby Ducks" uses one to threaten the duo after they crash his truck.

T-Word Euphemism: "How in the H are we gonna get rid of this S?" in the first episode. H is also used in later episodes.

Take That: Dude Time Cologne from "The Unicorns Have Got to Go" is a pretty clear parody of the advertising for AXE body spray. It's probably not a coincidence that it attracts Jerkass unicorns instead of hot ladies.

In "Video Game Wizard", when Rigby tries out the new power glove they won at a video game tournament, he notices how it doesn't work... just like the actual Power Glove. "Dude, this glove sucks!"

Temporal Paradox: This happens when Mordecai and Rigby refuse to lip sync a song that Future!Mordecai and Future!Rigby claim is not only the reason for their success, but entire existence. The two future beings then disappear after Mordecai breaks up the band.

Arguably Benson in his Day in The Limelight episode "Benson Be Gone", especially when he takes a limo and tries to run down the One-Winged Angel version of Susan. Leon takes his place at the last minute, but still!

Benson takes another level in badass in "Stick Hockey", where the titular game is apparently an underground bloodsport complete with rampant death, burning pits, and lots of spikes.

True Companions: There are moments when the group seems to be close to or evolving into this. While they don't always get along, they are shown to really care for one another at certain moments, such as Benson facing off against Susan to save them all and nearly making a Heroic Sacrifice to do so (Utopia took his place, but its clear) and the climax of "This Is My Jam", when Skips and the others come to help defeat the living Ear Worm without even being asked.

The Un-Reveal: The setting of the show. In "Prank Callers", after traveling back in time to 1982, the gang gets back to their own time by looking at which door holds their time period. Theirs is simply named "Present Day".

Unicorn: "The Unicorns Have Got to Go". They're punky/gothy Ambiguously Gay party animals who substitute periods with "bro" and are attracted by the scent of Dude Time Cologne. They also never say no to drag racing.

Vague Age: Averted in the first episode, where it's revealed Mordecai and Rigby are both 23 years old. The other characters, however, have no set age. The closest we know are from the storyboard artist's Formspring pages. Pops is over 100, Skips is hundreds of years old, and Benson is anywhere from 25-35.

Villainous Breakdown: In "Go Viral", The Warden of the Internet goes berserk after seeing that Mordecai and Rigby had freed all her prisoners.

Villain Team-Up: In "Skips Strikes", the bowling team Mordecai, Rigby, Skips, and Benson have to beat is made up of Death, the leader of the Guardians of Youth, Gary, and the wizard Rigby stole The Power from.

Rigby also has two Fist Pump toy guns that control figurative arm guns that fist pump.

Weirdness Magnet: Mordecai and Rigby. No matter how mundane their assigned task, no matter how minor their everyday, humdrum problem... they somehow find a way to transform it into a beautifully strange epic adventure.

Two in "Eggscellent": when Rigby falls into an allergy induced coma, Benson says that this should teach the others to not slack off their jobs and do something stupid. Mordecai decks him for this and tells him that the rest of the workers are just friends with him because he's their boss.

What Did I Do Last Night?: "Karaoke Video" starts out like this. Mordacai and Rigby don't remember saying any of the mean things to their co-workers while they sang "We're Not Gonna Take It" by Twisted Sister. They only find out when they replay the tape of their performance the next day.

Mordecai didn't remember ordering fake band t-shirts in "Mordecai and the Rigbys", either.

Skips quits the park bowling team and leaves his job altogether because he didn't want his friends to know that his name used to be "Walks" until he changed it due to the fact that he was tired of being asked "Why are you called Walks when you always skip?"

You can be sentenced to death for being too cool.
